hear plugs

I once borrowed a hearing aid from someone who was a bit deaf. I put it on for a while, and marveled at the full and distinct acoustic sounds that I could hear in ultra high quality audio. I'm now thinking I should invest in such a sound booster, and wear it when I go hiking. Since I am way more an audiophile than a videophile, the experience of listening to the spontaneous symphony of the forest with augmenting technology is very enticing.
